split

Reads the entire input at once and splits it using the input record separator (IRS) to obtain the records (rows). It
then splits the records using the input field separator (IFS) to acquire the fields (columns) of each record.

To decode the files, the L</File Encoding> is used.

Advantages:

=over

=item

The values assigned to the input record separator (IRS) and the input field separator (IFS) are treated as regex
patterns.

Template

Uses C<unpack> with the C<A> character to break up input lines.

=over

=item

If the row length exceeds the screen width, take note of the number of columns and the length of each column before
using I<Template>.

=item

Choose the input record separator.

=item

Set the number of columns (I<Col count>) and the width of the column separator (I<Sep width>). I<Col count> expects an
integer of 1 or greater; I<Sep width> expects an integer of 0 or greater.

=item

Set the widths of the columns (1 or greater). For the last column, one can also enter an asterisk (C<*>). An asterisk in
the last column means: Use the remaining part of the row for the last column.

=item

Decide whether leading spaces should be removed. Trailing whitespaces are removed automatically.

Advantages:

Ideal for fixed-length inputs containing only single-width characters.

Spreadsheet::Read

If C<Spreadsheet::Read> is chosen, the default settings from L<Spreadsheet::Read> are utilized.

C<Spreadsheet::Read> will use the first line of the file to auto-detect the separation character if the file is a CSV
file.

C<Spreadsheet::Read::rows> automatically fills up uneven rows, so the filters L</Fill up Rows> and L</Row Groups> have no
significance when C<Spreadsheet::Read> is used.

Advantages:

=item

Automatically detects the separation character for CSV files.
